If player comparing other casino is okay.
But while casino comparing their service with other casinos, is kinda such thing you should avoid for just safes way. Even you block the name site, we all know the picture is came from the stake. IMO and based of my experience, I have withdrawn activity more than a few thousand dollars in stake without any problem in single once from the beginning I play with them - now.
The same happened with other casinos from my experience (Roobet, Duelbit, Rollbits, Chips), off course without limited as well. Best answer and feedback is always from customer experience, I will see do we have some user who really brave and success withdraw a thousand dollar. If you can survive in casino industry and bring that quality with over a few years.
I'm sure your casino will be on the top priority list of some user. BTW about RTP issue, If you say some provider not provided the RTP but you as the casino should can ask right ? you using their service so you have some right to ask about that. If they can't provide you the RTP then simple, just skip to install the provider.
But based on my experience, almost every casino installed the same provider and all of them have RTP information. The only things different is, did the casino want to hide RTP or not.
